Thanks for everyone's posts. I surely didn't mean to abandon the post. Since my original post, Ford found that my transmission fluid was full of metal (bad news). So, they replaced the entire transmission. Well, I've been driving it for a couple of days and it sounds just like it did when I bought it. That is slightly better than the grinding evidenced in my video which was after I had driven it for about 6 months, but I think I'm back at square one. It has to be something in the way the computer is controlling the transmission. I fear it's just going to get worse again. I will be issuing a written notice offering a final attempt to repair under the Georgia Lemon Law. We'll see what happens.
This really sucks, because apart from the noise, which is causing damage to the transmission, I really like the car and love the fuel economy.
